Xen Summit 2026

The automotive industry is rapidly increasing its demand for hardware virtualization and is increasingly interested in the Xen Hypervisor as a key solution. This shift toward highly integrated systems introduces new challenges, particularly in thermal management, which are critical concerns for the automotive industry.
Xen hypervisor currently lacks a standardized framework for system-level thermal control, unlike traditional single-OS systems such as Linux. Thermal management in virtualized environments requires coordinated control across multiple components, but responsibilities are distributed across multiple layers—from firmware to hypervisor and operating systems—while no single component has full system visibility or authority over global coordination, where system-level control becomes significantly more difficult.
In this session, we present key challenges focusing on this gap and share our perspective on possible architectural directions, including a hybrid control approach that combines centralized policy concepts with distributed control. Through the session, we aim to engage the Xen community and encourage further exploration toward practical and standardized solutions.
